JamPlus

"Unknow rule" - How to read into it?

Hello, I am trying to compile this project - It compiles perfectly in Linux(ubuntu). But I want it to work on Windows. So I installed MinGW (which comes with Jamplus installed) - and went ahead installing all the libs needed for the project. After doing that (phew!) - I downloaded the src of this project and did './autogen' + './configure -prefix=/mingw' and then when I do jam, I get "unknown rule" warning. is it because they are unix commands and MinGW is not able to understand it?? Or is it jam?

Jamplus 0.3 the latest build ( not the next gen). I was just checking and in the linux VM where this project compiles correctly, I had Jam 2.5 installed. So I guess I will try installing Jam 2.5 in my MinGW installation and see.

Hence I tried autoreconf - which gave warning that "AC_BALLOC"(or whatever its called) was not defined but I check the mk folder where "balloc.m4" was present, when I googled it might be the case when its made from older version of the build tool. I could force to suppress the warning with "autoreconf -i" - But it fails in "./confugure" step stating AC_BALLOC not found.
